  • Real-time measurement/display/record/playback of wavefront data for use in vision correction procedures
    Patent number: 8820929
    Abstract: One embodiment is an apparatus/system for providing feedback to a procedure. The apparatus includes a real time wavefront sensor for measuring the wavefront of an optical beam, a real time video camera for capturing a scene where the optical beam comes from, a computer for processing the captured wavefront data and synchronizing the data with the video and outputting the synchronized information to a display, and a display for simultaneously displaying the synchronized wavefront and video information. Another embodiment of the present invention is a method for providing feedback to a procedure. The method involves the steps of measuring the wavefront of an optical beam with a real time wavefront sensor; capturing a video of a scene from which the optical beam comes; processing the captured wavefront data and synchronizing it with the video; and simultaneously displaying the wavefront information with the video on the same display screen.
